since tomorrow is my test. Please check:
seed coat- skin covering the seed to protect the inner parts
Hilum- ?
cotyledon- where nutritient is stored inside the seed
embryo- part of a seed that grows into a plant. it include roots, leaves, and stem?
I disagree with your first answer. Your other two are correct.
Yes, your explanations are mostly correct. I can help further explain the term "hilum" to you.
The hilum is a term used to refer to the scar on a seed where it was attached to the plant's ovary or the seed stalk. It is usually a small, distinct mark that is located on one end of the seed. The hilum serves as the point of attachment for the seed to the parent plant, through which it receives nutrients and water.
You can easily identify the hilum on a seed by looking for a small, usually round, indentation or scar. It is often lighter in color compared to the rest of the seed coat.
Understanding the different parts of a seed, such as the seed coat, hilum, cotyledon, and embryo, is crucial for comprehending the structure and function of seeds. Knowing this information will help you in understanding plant reproduction and development.
